The object of this invention is provide,

as a me'mber of a separately. formedattachable heel, alift'ineXpensively made from a box-toe skiving. i Such skiving, as iswell known, ,has a relatively long curvedvedge and a shorter edgeintersecting the endsfo'f the longer edge. The thickness of the skiving'gradually decreases from the said edges to the central portion, theedges being of sub lovstantial and uniform thicknessand each ofsubstantially the .samethickness as the other, and the centralportionbeing much thinner than the edge faces. A box-toe skiving is a wasteproduct which has been utilized here-,

tofore in the manufacture of heel rands, but not for operative heellifts. f

My invention consists in a blank characterized as above stated, andfurther characterized as hereinafter stated so that it is convertibleinto an operative heel lift having a continuous breast edge and aheelshaped marginaledge, andihereinafter referred to as a skiving lift.Of the accompanying drawings forming 2 a part of this specification,

The described skiving lift may-be utilized in buildingupv a cheap heelbody composed of a plurality of skiving lifts and a plurality ofordinary lifts 1 8, saidlifts' alternating, as shown by Figures 6 and 7.The lifts 18 may beof substantially the same thickness as the edges 15and 16 of the skiving'lifts.

, The heel body may be subjected to power-i ful compression to renderits opposite side surfaces substantially parallel with each 7 other andprovide a cheap heel blank or body of the pancake variety;

' Figures'8, 9,- '10 and; 11 showthe skiving lift as an element of aheelbase' which inapart sections extending'from the heel end to thebreast edge, each of said sections converging widthwise from the breasttoward the heel end, and at the breast, said sections being of suchwidth so that when 'brought together,vthe breast'corners of theblankwill approximately coincide with the respective breastcorners of theheellift into which the blank is to be formed.

Thearea of saidemension is indicated by dotted lines in'Figures 8 and 9,and the-formation' thereofreduces the thickness of the central portionof thebreastedge formed by the parts 16 so that the concave heel seatextends through the breast edge of the skiving lift;
